Shenzhen Zhongnuo Inspection & Technology Co., Ltd. specializes in consulting services for the explosion-proof CCC certification. We have a wealth of consulting cases in the field of explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide clients with consulting services such as application assistance and factory audit guidance.
How to obtain certification for explosion-proof electrical products not listed in the CCC explosion-proof product catalog?
ZhongNuo Inspection: Currently, the product catalog only includes most explosion-proof electrical equipment. However, certain types of equipment, such as large-scale system devices and explosion-proof lighting, are not listed. These still require the original process of applying for an explosion-proof certificate and obtaining the certificate before they can be used in hazardous explosive areas.

How can a company apply for the explosion-proof CCC certification?
1. Self-Application: Companies apply directly to the certification body, independently prepare relevant documents, assist in debugging prototypes, and revise any non-standard parts in the documents. This process is relatively time-consuming and has a higher overall cost, requiring both time and effort.
2. Agent Application: The application process involves a specialized explosion-proof electrical technology consulting service agency (such as Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.) handling the entire consultation and application process, including material modifications, prototype debugging, and progress coordination. This ensures a good progress guarantee. Fast certification, controllable comprehensive costs, and time-saving efforts.

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof compliance certificate?
ZhongNuo Inspection: Since the release in July 2019 regarding explosion-proof electrical products and more in the market
Following the announcement of mandatory product certification management implementation requirements after the transition from production license to mandatory product certification management,
Many companies producing explosion-proof electrical products have gained a certain understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof qualification certificate?
Actually, a careful reading of this announcement reveals that only certain explosion-proof electrical products are included in the scope of mandatory product certification (for details, see the product catalog for mandatory explosion-proof electrical product certification).
There are still a large number of explosion-proof products not included in the market, such as common pressure transmitters, combustible gas detectors, breathing valves, intelligent scanning terminals, dust removal equipment, and mechanical products, etc.
Extraneous explosion-proof equipment installed in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards and obtain the corresponding explosion-proof certification.

Requirements for application of the explosion-proof CCC certification:
1. Product Drawings and Documents: When an enterprise applies for a explosion-proof certification for intrinsically safe electrical equipment, it should provide assembly drawings, circuit diagrams, printed circuit board diagrams, silk-screening diagrams, material lists of components, and label diagrams, etc. For non-intrinsically safe electrical equipment, the technical documents submitted for inspection should include drawings that reflect the explosion-proof performance of the sample (including assembly drawings and component drawings). If the assembly drawing can clearly indicate the explosion-proof parameters and structure of the product, only the assembly drawing needs to be submitted for inspection.
2. Technical Documents: Include company standards/technical requirements. The company standards/technical requirements for the product should be written in the prescribed format, and their content should not only include performance requirements of the product but also cover related aspects of explosion-proof: such as basic parameters, explosion-proof markings, operating environmental conditions, explosion-proof performance requirements, relevant tests for explosion-proof performance, and markings related to explosion-proof.
3. Additional Information: For products with adhesive bonding or casting, provide the model names, performance descriptions, and relevant process documents for the adhesives and casting agents. For plastic casing products, supply the material type and corresponding performance documents. Battery-operated products require the battery specifications to be provided as well.
